This invention relates toclips orfasteners, and with regard to certain more specific featuresV to fasteners for building construction and the like.

5 Among the several objects of the invention may be noted the lprovision of fastening means adapted to be applied directly to concrete, gypsum andglike hard surfaces directly by means of blows and without other compli- G cated movements; the provision of an article of manufacture of the classdescribed which is delivered to the user-with the fastening means assembled and set for driving; andthe provision of a device of the class described l5 which is applicable to the device to which it is fastened with a minimum of complication. Other objects willbe in part obvious and in part pointed lout hereinafter.

The invention accordingly comprises the 0 elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structure hereinafter described, and the scope of A the application of which will be indicated 53) in the following claims.

In the accompanying drawings in which isk illustrated one of various possible embodiments of the invention, Y

Fig. l is a plan view of a form of the in# "5 vention adapted to hold metal corner beads in place;

Fig. 2 is a side elevation of Fig. l; Fig. 3 is a plan view showing the device of Figs. l and 2 applied to a metal corner bead; 35 Fig. 4 is a cross section taken on line 4--4 of Fig. 3 and Fig. 5 is a layout showing the economical manner in which the devices shown in Figs.

l to 4 are manufactured.

Similar reference characters indicate corresponding parts throughout the several views of the drawings;

Referring now more particularly to Fig. l, d there is illustrated at numeral l a blank com- 3 posed preferably of sheet metal having a more or less rectangular body portion 3y and a finger 5, the body portion and linger being so symmetrically shaped that they may be stamped from a single strip in the nested ar- 1 openings 17 holes provided Vwhich are to go through them, the fasteners j rangement illustrated in Fig. 5. As willbe `seen from said` 5, the shaping is arrangedto eliminate all waste of material, the

i cut-out portion'on each side of each Vlinger ccmprising one-half of the space required for shaping the linger onan adjacent'nested 55 blank. The body portions are arranged `along each side of .the strip in staggered arrangement. i

Each blank lis provided at its body portion 3 with up struck tongues 7 and 9, one of 60 which tongues?q is open in a direction opposite to the opening of the other tongue 9. The open ends of the tongues'are each provided with'bent up portions `l1 for facilitating ap-. plication of the deviceQ." t will be seen by 65 reference to Fig. 3 that cornerbeadsl, such as are used in plastering construction and the 'like have edges l5 and suitable openings 17,V

so that by suitably positioning the blank l, i the tongue 9 may beV hooked intoone of the 70 and the tongue7l hooked under an edge l5.

Heretofore with structures of thisclass, there have only been-openingsfsuch as nail for the fasteners or the like .75

After getting the blank-1 into the position above described,.onjthe corner bead, the user S0 was required to hold` the blank` and apply a nail or the like through the opening, all with one hand,.so that the other hand, holding a hammer orthelike', mightbe used to drive home the fastening nail or the like. The re- 85 sult was that fingers werev'often injured because ofthe necessity fordoing three things.v Y with onlyrtwo Ahands!l v l have overcome'the `above Idifficulties by providing the 'lingers 5 with pressed-Quail@ hollow domes or cones` 19,each having an opening 2l atits apeX for the purpose of` snugly receivinga nail 23. vltl will be appreciated that the openings 21 inay be'made somewhat smaller than the nails so that thef 95 Y platter may at the :point vof manufacture be driven partially lhome (preferably automatically) ,so as to remain assembled and snugly The metal 27 which fitting in the openings.v

Hence only two operations are required which may be performed two hands. An advantage is that the nails are held in a more rigid position than when held' by hand which lng driven into.

, Another advantage of a corner Vbead clip of ythis type rests in theease with which it may be attached to the corner bead and nailed to the concrete. In the course of erection of corner beads it will eliminate the tedious operation of fastening `the nails through the corner beadclip, as well as the danger of striking finger tips-in the vattempt to start .and to drive the comparatively short, stub Y nails used for this purpose.

The nails 23 are composed preferably of hardened I material, adapted to be driven without bending directly into hard and brittle materials such Vas concrete or gypsum.
